IPC: G03F7/20
Filed: 2000-03-23
Abstract: PROBLEM TO BE SOLVED: To provide a charged-particle-beam exposure apparatus wherein the positional discrepancy and blooming of the image of its beam are scarcely generated even when the temperature in its lens barrel is varied. SOLUTION: After projecting an electron beam on a reticle 3 by an illumination optical system, the electron beam passed through a pattern formed on the reticle 3 is imaged on a wafer by two lenses 1, 2.

Ferrite stacks 9, 10 prevent the deflectors 7, 8 from causing unintended magnetic actions on the electron beam by eddy currents occurring in the constituent metals of the lenses 1, 2 due to the effect of the AC magnetic fields generated by the deflectors 7, 8. The permeability variations of the used ferrite stacks 9, 10 are so made small that the positional discrepancy of the image of the electron beam which is caused by the permeability variations of the ferrite stacks 9, 10 due to their temperature variations becomes not larger than a predetermined value.
